SPRAY Nozznn Application led January 13, 1921. Serial No.- 436,930.

To all whom t my concern.'

Be it known that I, FRANK W. HENRIK- SON, a citizen of the United States, residing at Mulberr in the county of Crawford and State of l ansas, have invented .a certain new and useful Improvement in Spray Nozzles, of which the following is a specification.

My invention relates to improvements in spray nozzles.

It is particularly adapted for use in connection with a shower bath mechanism.

One of the objects of my invention is to provide a novel nozzle from which the discharge of liquid may bereadily controlled ald which is self cleaning and not liable to c og. y A

The novel featuresl of my invention are hereinafter fully described and claimed.

1n the accompanying drawing, which illustratesthe preferred embodiment of my invention as applied to a shower bath,

Fig. 1 is an enlarged central vertical sectional view of my improved'nozzle. v

Fig. 2 is a top view with the body` of the nozzle removed.

Fig. 3 is a bottom view of the nozzle.

Fig. 4 is a side elevation of the, rotary member.

Fig. 5 is a side elevation, reduced, of iny improved nozzle shown used in connection with a shower bath mechanism.

Similar reference characters designate similar parts in the different views'. The nozzle comprises a tubulargbody 1,

having an internally screw threaded upper end adapted to have fitted therein a vwater i e 2.l

p Xtending transversely across the lower discharge end of the body 1 is a perforate discharge plate 3, which is preferably concavo-convex, the concave' side being the inner side. The perforations 4 of the.y plate 3, preferably, diverge downwardly, so as to throw the water outwardly.

The plate 8 is releasabflyclamped to the lower end of the body 1 by a screw cap.

5 fitted to the body 1 and having alarge central opening 6.

Extending inwardly from and secured centrall to the plate 3 is a longitudinal pin 7 on vwhic ispivoted a transverse valve member arranged to close the perforations 4 and coma concavo-convex valve risin referabl p g p iii inner side of the plate vplate 8 fitted to t 3 and centrally pivoted on the pin 7 and having downwardl diverging `perforations' 9 arranged to be rought into, and out of register with the perforations 4 by a pin 10 which extends downwardly through a slot l1 provided in the plate 3 and which has its upper end, attached to the valve plate 8.

A rotary vmember which is Arotatable by water passing through the body 1 and plates 8`and 3 is rotatably mounted on the pin 7, in contact, preferably, with the plate 8. This rotary member comprises, preferably, a hub portion 12 which is rotatable on the pin 7 and from which extends outwardly obliquely disposed propeller blades 13 which bear against the upper side of the plate 8. A ring 14 is connected to the outer ends, of the blades 13, and at intervals is spaced apart from the plate 8.

Then the valve plate 8 is moved by means of the pin 10 to the discharge position shown in Fig. 1, and water is permitted to passdownwardly through the pipe 2 and body 1, the water willstrike the blades 13, thereby rotating the rotary member. The 80 revolving movement of the blades'13 will keep the upper surface of the plate 8 clear of sediment, so that the perforations '9 and 4 will not become clo ged. The revolving movement of the bla es willalso tend to.l effect a Vbetter diffusion and breaking up of the water as it is discharged from the nozzle. y

By proper adjustment of the valveplate 8, the discharge of water from the nozzle emay be regulated or entirely shut o.

1n Fig. 5 my improved nozzle is shown applied to a shower bath mechanism in which thewater is supplied to the 'pipe2 by a valve casing l5 that maybe supplied by two pipes 16 and 17 with hot and cold water.

The nozzle is disposed above a treadle 18 .which is connected by a rod 19 with a lever 20 which is movable in one direction by the 100 rod 19 and in the opposite direction by a vsuitably supported spring 21. The lever 20 operates suitable valve mechanism for controlling the supply of water conveyed to the nozzle bythe pipe 2. ing under the nozzle may with the treadle l8control the discharge of water from the nozzle.v The water passing through the nozzle will revolve the blades 13, thus'keeping the upper surface of the valve plate 8 110 A person standclear of sedimentand -eecting a thorough breaking up and diiusion of the Water discharged from the nozzle.

ll do not limit my invention to the structure shown and described, as many modifications Within the scope of the appended claims, may be made Without departing from the spirit of my invention.

l`What l claim is.

1. A. spray nozzle comprising a tubular body, a perforate discharge plate at the discharge end of 'the body, a rotary member in said body at the inner side of and adjacent to said plate, and a valve intermediate of said rotary'member and said perforate' plate for closing the perforations of said plate and against which the rotary member revolves, said rotary member being adapted to be rotated by fluid passing` through said body and said plate, substantially as set forth.

2. A spray nozzlecomprising a tubular body, a perforate discharge plate at the discharge end of said body, a rotary member in said body at the inner side of andadjacent to said plate and arranged to be rotated by fluid passing through said body and said plate, and a perforate valve plate intermediate of the discharge plate and the rotary member and against which the latter revolves and arranged to close the openings of the discharge plate, substantially as set forth. y

3. A spray nozzle comprising a tubular body, a perforate discharge plate at the discharge end of said body, a pin extending in- Wardly from and supported by said plate, a rotary member rotatable on said pin adjacent to said plate by fluid passing through said body and said plate, and a valve pivoted on said pin intermediate of said plate and said rotary member for closing the perforations of said plate and against Which the rotary member revolves, substantially as set forth. n

4. A spray nozzle comprising a tubular body, a perforate discharge plate at the discharge end of said body, a perforate valve plate at the inner side of the discharge plate lmovable to and from a position in which it will close the perforations of said discharge plate, and a rotary member at the inner side of said valve plate having one or more propeller blades bearing against the valve plate and arranged to revolve the rotary member when struck by uid passing through the meegaat body and said discharge plate, substantially' as set forth.

5. A spray nozzle comprising a tubular body, a perforate discharge plate at the discharge end of said body, a pin extending inwardly from and supported by said plate, a perforate valve plate at the inner side of said discharge plate movable on said pin to. and from a position in Which it will close the perforations of said discharge plate, andv a member rotatable on said pin and having one or more obliquely disposed propeller blades bearing against the inner side of said valve plate and arranged to revolve the rotary member when struck by fluid passing through said body and said discharge plate, substantially as set forth.

6. A spray nozzle comprising a tubular body, a perforate discharge plate at the discharge end of said body and having a slot, a pin extending inwardly from and supported by said plate, a perforate valve plate rotatable on said pin at the inner side of said `discharge plate and having a pin extending outwardly through said slot, the valve plate being arranged to close the perforations of said discharge plate, and a rotary member revoluble on the first named pin and having one or more propelling blades lbearing against the inner side of thevalve plate, substantially as set forth.

7. A spray nozzle comprising a tubular body, a discharge plate at the discharge end of said body having discharge perforations, a valve member at the inner side of said plate movable to and from a position closing said perforations, and a rotary member at the inner side of said valve member having a plurality of oblique propeller blades bearingr against said valve member and having a ring connected to the outer ends of .said blades and spacedapart from said valve member, substantially as set forth.

8. A spray nozzle comprising a 'tubular body, a perforate plate in the discharge end of the body, and a rotary member in saidA body having one or more obliquely disposed propeller blades bearing against the inner side of said perforate plate and arranged to revolve the rotarymember. when struck by a fluid passing through said body and through said yperorate plate, substantially as set forth.
